If you have an MSDN subscription, you know that it provides a number of benefits besides software licenses - you get Azure hours, you can use Visual Studio Online, and so on. Those are well worth the price of the subscription. But it also gives you access to a number of Pluralsight courses, completely free. If you have a Professional Subscription, you get access to 30 courses, and if you have an Enterprise subscription, you get access to 45 courses. (You want one of the over 4500 other courses? You'll need a full subscription, but you can buy that at 30% off, which helps.)
